Description
Eight test pits (0.8 x 0.3m) were excavated by Colchester Archaeological Trust in February 2011 prior to the installation of new pathways for vehicular access and new metal fencing in the nursery area and on the former putting green in (the northern half of) Hollytrees Meadow, Castle Park, Colchester. <1>
The test-pits were mostly excavated through modern topsoil and post-Roman dark earth containing frequent Roman artefacts. The quantities of Roman tile, pottery and tesserae hint at Roman occupation features in the vicinity and below the limit of excavation.
Roman archaeology was uncovered in four of the 2011 test-pits at depths of between 540mm and 590mm below modern ground level. The east-west orientated Roman street between Insula 7 and Insula 15 was identified in Test Pit 8.
In Test-Pit 1 another metalled surface was uncovered at a depth of 590mm below modern ground level. The stones were not as densely or as firmly bedded in this surface as they were in the Roman street surfaces identified in TP8. Probable Roman deposits were alsoidentified in the two test-pits located near to Duncan’s Gate. A light coloured sandy silt layer containing frequent stones and fragments of oyster shell was uncovered inTP3 (550mm below modern ground level) and a layer of mortar containing fragments of building materials was uncovered in TP4 (590mm below modern ground level). Both are presumed to be the upper layers of Roman deposits.
In TP5 and TP6 a dark yellow/brown sandy clay was identified at a depth that prohibited positive identification as an archaeological deposit (850mm and 940mm below modern ground level respectively). The sandy clay may be the natural geology. At a depth of 610mm below modern ground level a large water main was encountered in TP2. A notable number of tesserae were recovered from the backfill material of the pipe trench. The test-pit excavated on the former putting green (TP7) was excavated to a depth of 1m below modern ground level through dark soil. No archaeological deposits were encountered, matching the findings of previous test-pits excavated on the former putting green (CAT Report 422). <2>
All eight of the test-pits were excavated through a dark grey/brown sandy silt. This soil is considered to be a modern topsoil overlying a post-Roman dark earth. There is very little distinction between the two layers and in many locations the soil has been heavily disturbed.
Almost all of the finds recovered from the eight 2011 test-pits are of Roman date and include pottery sherds, fragments of roof tiles (tegula and imbrex), a piece from a combed flue tile (TP3) and notably a number of red tile tesserae from a tessellated floor surface (TP2, 3, 4 & 6). The tesserae range in size from approximately 15 to 25mm square. One (TP4) has been cut from a combed flue tile. Of interest is a small copper-alloy object (8mm in diameter) from TP4 which is almost certainly a coin (SF 1). The surface is corroded so the coin cannot be identified in its present condition but the size and the presence of late Roman pottery suggests it is probably a small late Roman coin of late 3rd-4th century date. Single sherds of medieval pottery were recovered from two of the test-pits (TP3 & 8) and post-medieval/modern artefacts were collected from TP4 and TP2.
Of particular note is the presence of part of a human pelvis in TP7. Investigations at the time confirmed that the pelvis was not part of an articulated skeleton.
